When the glass is turned over, sand runs from the top to the bottom.Radioactive atoms are like individual grains of sand--radioactive decays are like the falling of grains from the top to the bottom of the glass.Radiometric dating techniques indicate that the Earth is thousands of times older than that--approximately four and a half billion years old.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.The goal is to promote greater understanding on this issue, particularly for the Christian community.Some of the atoms eventually change from one element to another by a process called radioactive decay.If there are a lot of atoms of the original element, called the parent element, the atoms decay to another element, called the daughter element, at a predictable rate.
